Basically, Yahoo insists that their own mail servers are the only ones that can originate the message with @yahoo.com domain in the From header. Not Return-Path, Not the envelope sender, but exactly the From header in the message itself. If this practice gets adopted by more organizations, I don't know how else could this problem be solved. -- Pozdrav / Regards, Siniša Burina -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org

Well, anonymous_list option does that too, completely hiding the original poster's information. The approach I proposed would do the same, only in slightly subtler manner. :) -- Pozdrav / Regards, Siniša Burina -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
[Mailman-Users] DMARC issues
Hello! I believe there's no need to elaborate on the problems recently introduced by Yahoo, changing their DMARC DNS record and rendering many mailman lists unusable for Yahoo mail users. I see the solution to this problem in changing the From: field to mailing list's address, but keeping the poster's name or address in the description part of the same field. For example: From: "List Name on behalf of Poster Name" or From: "Poster Name via List Name" or From: "Poster Name" or From: "Poster Name [pos...@add.re.ss]" I'm using Mailman 2.1.13, and can not upgrade to 2.1.16 on a live system. I was forced to turn on anonymous_list as the urgent remedy, byt the full anonymization is not really how it should be. Could someone please help me achieve this using the above version, by some changes in the code? Thank you! -- Pozdrav / Regards, Siniša Burina -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
